In the early pregnancy, in addition to the necessary blood tests (blood routine, blood type, A, B, hepatitis C antibody, AIDS antibody, syphilis antibody, liver function), during the pregnancy 10 ~ 14 weeks, some hospitals may do B-ultrasound examination for you to check the zona pellucida of the fetus and other signs of suspected chromosomal abnormalities, so as to judge whether the baby is abnormal or not.
If there are abnormal conditions such as vaginal bleeding and abdominal pain, we will check whether there are abnormal conditions such as abortion, ectopic pregnancy and hydatidiform mole through B-ultrasound and hormone determination. Other tests include rubella virus screening, Toxoplasma antibody screening, cytomegalovirus screening or other pathogen screening, and other related tests such as renal function, blood lipid and blood syrup according to your personal health history.
Prenatal check-up in the second trimester (pregnancy 14~27(+6 days) weeks)
In the second trimester, except for some special circumstances or complications, as well as situations that require more examinations, such as hypertension, it is generally necessary to go to the hospital for a prenatal examination once a month.
In the second trimester, the doctor will not only ask about you and the fetus, but also conduct routine examinations (record your weight, blood pressure, edema, measure your uterus height and abdominal circumference, and check your baby's fetal position; Listen to the baby's fetal heart rate with Doppler fetal heart rate; Arrange your blood test, urine test and other related inspection and laboratory procedures), and discuss with you to arrange some corresponding inspection and laboratory procedures according to your gestational age and specific situation.
From 0/4 to 20 weeks of pregnancy/kloc-,the doctor will usually arrange a blood screening for down syndrome for you with your consent. Down syndrome is one of the most common chromosomal abnormalities. Generally, older women over the age of 35 are more likely to suffer from Down syndrome than younger women.
If your screening results for Down syndrome show high risk, or there are other indications, the doctor will usually discuss with you and arrange amniocentesis for you. This is a kind of examination to extract amniotic fluid from your uterus, make fetal chromosome or immune, biochemical and genetic analysis, and diagnose whether the fetus has chromosome abnormality, other genetic diseases or intrauterine infection.
About 20 ~ 24 weeks pregnant, the doctor will advise you to do a detailed B-ultrasound examination to see if the baby has any abnormal morphological structure, such as cleft lip and congenital heart disease, and to understand whether the growth and development of the fetus is in line with the month of pregnancy.
During the 24th to 28th week of pregnancy, you will undergo a 50g glucose challenge test (also known as glucose screening), which is a blood test to screen whether you are at risk of gestational diabetes.
Prenatal check-up in the third trimester (28 weeks before delivery)
In the third trimester, prenatal examination is usually done every two weeks from 28 to 36 weeks, and once a week after 36 weeks. Routine examination (record your weight, blood pressure, edema, measure uterine height and abdominal circumference, and check your baby's fetal position; Listen to the baby's fetal heart rate with Doppler fetal heart rate)
Ask about the baby's fetal movement. B-ultrasound in the third trimester. After 28 weeks of pregnancy, doctors will generally advise you to do a B-ultrasound in the third trimester to check the growth and development of the fetus, amniotic fluid volume and fetal position, and make a diagnosis of late dominant malformation.
Fetal heart monitoring: From the 37th week of pregnancy, the doctor will arrange for you to have fetal heart monitoring at each prenatal examination.
In the third trimester, the doctor will also carry out blood tests such as liver function, kidney and blood sugar according to your situation.
What prenatal examinations are necessary? Health experts discussed and studied the essential prenatal examination during pregnancy, which should include the following contents:
In the early pregnancy, at least one comprehensive physical examination, necessary examination, psychological status and pregnancy status evaluation and health care guidance should be carried out.
In the second trimester, fetal quality screening should be conducted, including informed consent screening for Down syndrome.
From 20 to 24 weeks of pregnancy, systematic screening and B-ultrasound were performed to monitor fetal growth and development.
At least 2 ~ 3 prenatal examinations should be conducted in the third trimester, one of which should be 36 weeks or later, and delivery plans should be made, including at least one B-ultrasound to understand the growth and development of the fetus, fetal position, placenta and amniotic fluid.
Routine hematuria is essential during prenatal examination, and anemia, thrombocytopenia or urinary protein can be found in time.
